A house that sat quiet through the winter can host surprises when you turn the water on and air the rooms out. Mice do not need an invitation card, and ants are happy to follow the first crumb someone drops on the counter. If you are opening a seasonal or second home in Southampton, East Hampton, Sag Harbor, or anywhere along the East End, a short pest-focused walkthrough saves you from playing catch-up in July.
Start Outside Before You Unpack
Walk the perimeter. Look for gaps where utilities enter, loose vent screens, and rotted sill areas. Mice squeeze through openings you can miss if you are only looking at the front door. Note any mud tubes or damaged wood at the foundation—those belong in a termite conversation, not a DIY shrug.
Check gutters and downspouts. Leaves from last fall may still be blocking flow. Water that sits in the gutter is a mosquito nursery; the same maintenance that protects the roof also supports what we cover in standing water and mosquitoes.
Scan the yard and beds. Tall grass at the edge of woods is prime tick habitat. You do not have to solve the whole landscape on day one, but mowing and clearing debris near paths and play areas should be on the list before kids and dogs settle in. If the property backs to brush, plan tick control for the weeks ahead, not the middle of August.
Look under decks and sheds. Tipped garbage, burrows, or torn lattice often mean raccoons, skunks, or other nuisance wildlife while you were away. Wildlife control is built for that situation—trapping and exclusion beat guessing from a flashlight at midnight.
Inside: Signs You Were Not Alone
Kitchen and pantry. Droppings in drawers, gnawed packaging, or a stale smell in a cabinet point to rodents. Even if you do not see a mouse, the evidence matters. General insect and rodent control includes inspection, treatment, and guidance on entry points so you are not resetting traps every weekend.
Basement and garage. Cobwebs are normal; a trail of ants from a crack in the slab is a map to where they are entering. Seasonal homes often get ants first in utility areas where temperature changes create small gaps.
Attic if you have safe access. Insulation that is disturbed, nesting material, or scratching sounds should be checked by a professional before you assume it is “just wind.”
Timing Your First Professional Visit
You do not need to wait until something is crawling across the counter. Many second-home owners line up a seasonal program that runs from late spring through fall, then add mosquito control or tick visits based on how the property is used. Opening weekend is a good moment to request a quote so treatments align with when you are actually on site—not three weeks after the bugs already moved in.
